On July 26, 2019, at 2:05 p.m. PDT, we received reports that some users were unable to connect to Slack. Upon investigation, we learned that our latest code change was incompatible with the desktop app versions 3.2.0 or older. The result was that users trying to connect to Slack using these older apps were unable to do so. We identified the problem and reverted this code change. The issue was fully resolved by 3.42 p.m. PDT.

We are happy to report this issue has been resolved, users running desktop app v 3.2.0 or older should be back up and running. Apologies for any disruption to your day.

3:46 PM PST

We're still trying to pin down the root cause of the desktop app v 3.2.0 and older failing to connect. In the meantime, please update the app to get things running again. Apologies for any disruption to your day.

On July 26 from 05:00 a.m. PDT, some users began to experience connectivity issues. This was determined to have been caused in part by a code change published the night before. While reverting this change and attempting to recover from its downstream effects, users began to experience failures while sending messages as an unintended side effect. As a result, we rolled back this attempted fix and began applying it again, this time more slowly, bringing full recovery to impacted users by 10:25 a.m. PDT.

2:27 PM PST

Things should be back to normal and users should no longer see issues connecting. If you're still having troubles, let us know at feedback@slack.com.
